.CORPORATION OF PENNSYLVANIA.

TOY TOBPEDO.

Application tiled March l5, 1921. Serial No. 452,466.

T o all whom z'tmay concern Be it known that I CAMILLO MACCHIA, a citizen of the United tates of America, and resident of Ardmore, in the county of Mont' gomery, State of Pennsylvania, have invented a, certain new and useful Improvement in Toy Torpedoes, of which the following is a true and exact description, refer;- ence being had to the accompanying drawin which forms a part thereof.

y invention relates to torpedoes of the kind intended to be exploded on being thrown against the ground or a wall and the object of my invention is to provide such a torpedo with a definite holding capacity for the explosion and vel forming its charge and a wall strengtrgvhich can be accurately determined and which will insure sufficient resistance to the expansive 'power of the gases generated when the explosive is ignited to insure that when the container bursts a loud explosive noise will occur.

The nature of my improvement will be best understood as described in connection with the drawing in which Figure 1 is a vertical central sectional elevation of my torpedo, and

Figure 2 a section on line 2--2 of Fig. l.

A is a cylindrical container formed of multiple windings of paper indicated' at a, a. B and B are cup like closures of a strong tough material formed with peripheral flanges b, b' which t over the ends of the container A. The closures B, B', must be strong enough to offer a resistance to a bursting strain equal to that necessary to insure the volume of sound desired on the explosion of the torpedo. 'C, indicates the charge of explosive in the torpedo and D the charge of gravel with which the explosive container is loosely filled. E is the outer wrapping of the torpedo made up of multi le windin s e, e, of paper glued together an glued to t e container A and the lian es b and b of the closures B, B. The tu ular wrapper E being made suiricientl strong and suliciently rml attached to t e closures to insure that the c osures will not be blown oii' of the ends of the container when the explosive is ignited and therefore to insure that the expanding gases will burst through the wall of the container or through the heads of the closures or both.

I In constructing m torpedo the container i Ais formed by win ing a strip of paper on a mandrel the windings e being at least partly secured together by glue, a closure B is slipped over the lower end of the container and a measured charge C of explosive inserted, after which the container is filled up with ravel and a closure B slipped over its top. inally, a strip of paper glued on its inside is wound around the container and the anges b and b of the closures forming an outer tubular wrapper E made up of multiple windings e of paper strong enough and strongly enou h attached to the closure flanges to prevent t eir being blown off when the explosive ignites.

By preference the strength of the wallof the container A together with the strength of the wrapper E should be about ual to that of the closures so that the hea s and walls of the container will as nearly as possible burst at the same time.

It -will be obvious that my torpedoes are of equal capacity, symmetrical shape, easily and safety transportable and so designed as to insure uniform explosive qualities and a maximum noise on explosion.

Having now described my invention, what- I claim as new and desire to secure by Letters Patent, is:

1. A to edo consistin of a cylindrical container ormed of mu tiple windin s of paper, cup like closures for the ends o said container formed of strong, tough material flanged to fit over the ends of the container, a wrapper formed of multiple windings of paper glued to the outer wall of the container and to the flanges of the closures, the windings of said wrapper being glued together and a charge consisting of an explosive powder and gravel filling the container.

2. A toy torpedo comprising a paper shell consisting of a short length of tube, snugly it'ting anged cap members secured toi the fitting cap members having flanges glued to ends of the tube and forming closures at the outer surfaces at the ends of the tube and each endv thereof, 'anda mixture contained forming closures at each end thereof, and a'. 10 therein adapted to be exploded when the tormixture contained therein adapted to be ex- 6 pedo is` subjected to shock.v dploded whenthe -torpedo 'is subjected to.

3. A toy torpedo comprising al paper shell shock. consisting of n Short length of tube, snugly CAMILLO MACCHIA.
